RAY E. MANSON; OF ROCHESTER, N-EW YORK, ASSIGNOR TO THESTROMBERG-CABLSON TELEPEONE MANUFACTURING COMPANY, OF ROCEESTER, NEW

TION OF NEW YORK.

YORK, A CORPORA- VACUUM-TUBE SOCKET.

Application filed August 26, 1925, Se'a No. 52,675.

This invention relates to sockets for electrcal devices and moreparticularly to sockets for use in connection with vacuum tubes.

Tube sockets of the prior art have been expensive 'to manufactu'e, arebulky for shipment and require a large amount of space in a radiocabinet.

It is the purpose of the present inventio to provide a vacuum tubesocket, which is simple and inexpensive to manufacture, and whichrequires a minimum amount of space.

Referring to the drawings, Fig. 1 represents a top view' of a shelf onwhich the socket is mounted. Fi'g. 2 shows a side view of the shelf witha socket mounted thereon and a portion of a vacuum tube for usetherewith. Fig. 3 is a bottom View ofthe shelf and socket, while Fig. 4is a view of a terminal for use in the socket.

In the drawings, 5 desi nates a shelf which may be part of a radio setor other device in which vacuum tubes are mounted. N ear the center ofthis shelf there are pro- Vided two large holes 6 and two small holes 7,which are spaced as indicated in F ig. 1. These openings are of suchsize and are spaced at proper distances to receive similar sized andcorresponding-ly spaced contacts 30 of a vacuum tube 31 partiall shownin F ig. 2. On the lower side of the shelf 5, there is mounted a socket,which consists of a disk 8 of insulating material, provided with fourrectangular `openings *9 and four round openings 10 to receive fourterminals 11 of conductng material of the 'form shown in F ig. 4. Eachof these terminals' is apertured at 13 and is provided with a-pair ofprongs 12 adjacent said aperture for insertion in the openings 9. Otheropenings 14: inthe terminals register with the four round openings 10 indisk 8 when the terminals 11 with their prongs 12 are inserted in therectangular openings of the disk. These terminals are held in fixedrelation by e elets passing through openings 10 in the isk 8 andopenings 14 in termnals 11, while bolts 151 passing through openings 15and shelf 5 and through eyelets 16, hold the socket in spaced relationwith respect to the shelf 5. Lugs 18 on terminals 11 provide aconvenient surface to which electrical conductors ...ay be soldered. v

In' use, a pair of prongs 12 of a terminal 11 engage opposite sides ofeach contact 30 when the vacuum tube 31 is inserted in the socket fromwhich it will be recognized that the prongs aline themselves withrespect to the contact with a minimum amount of tension or distortion onthe body of the termi- 'ings being in registry with said first men-.toned openings, terminals mounted between said support and said disk,resilient prongs on each terminal and projecting through the'rectangular openings in said disk, each of said terminals havn a pairof openings therein, one of which s between said prongs and the otheropening in registry with the circular Opening in sad disk, means passingthrough the circular openings in said disk and through the lastmentioned openings in said terminals for securing said terminals to saiddisk, and means for securing said disk to said support.

2. In combination with a support having openings of different areas toreceive the terminals of a vacuum tube, a circular plate of insulatingmaterial having pairs of radially positioned openingstherein, the firstOpening of each pair being rectangular, said rectangular openngs beingin registry with said first mentioned openings, terminal strips mountedbetween said support and said plate, resilient prongs on each terminalstri shaped in rectangular form and projectn through the rectangularopenings in said p ate, each of said terminal stri shaving` a pair ofopenings therein, one o which is between said prongs and the otheropenin in registry with the second Opening in sai plate, means assingt-hrough the second openings in sad plate and through the last mentionedopenings in said termnal strips for securing said terminal strips to sadplate, and means for securing said plate to said* support.

In witness whereof, I he'eunto subscribe' my name this 21st day ofAugust, A. D.
